In my admin, I want my "slug" field to be prepopulated with the 'name' field. I'm using the below code but it isn't working. Maybe I should be importing the prepopulated field? Please let me know if you have any advice. I left out some of the code but I think I included all that's needed to debug the problem. Let me know if you require any additional information though. Thanks!
